. WATER-GAGE;

To all whom it may concern Be it known that I, MICHAEL W. SHIPP, a

citizen of the United States, residing at Wilkes-Barre, in the county of Luzerne and State of Pennsylvania, have invented new and useful Improvements in Water-Gages,

of which the following is a specification.

This invention relates to a water gage and in particular to the type of gage wherein the of the same,'the body portion'of the wedge water glass is in the form of a plate or bar of sufficient thickness to withstand the pressure to which such a gage is ordinarily subjected. Ina gage of this type,*the water glass is usually clamped in position by means of'a securing plate having clamping bolts connected therewith at spaced points.

This construction is objectionable in that there will be portions of the glass wh ch are] not secured tight. enough to the body 'of the gage and will be apt to yield to the pressure;

It is thepurpose of my invention to provide. a gage wherein the water glass 'is clamped in position bymeans of a wedge device which will bind'the glass with uniform pressure throughout its entire area.

A further object of the invention is to provide a gage'devioe of this character wherein the wedging device is constructed so thatit will bind the glass effectively throughout 1138 entire length even though the latter may be slightly toward one of its ends.

The invention consists in the features of 1 construction, combination, and arrangement of parts, hereinafter fully described and claimed,: reference being hadto the accompanying drawings, in which: v

Figure 1 is a side elevation of the gage'in use; Fig. 2 is a top plan view of the same; Fig. 3 is a bottom plan view; Fig. 4; is a longitudinal sectional view taken therethrough; Fig. 5 is a transverse' sectional view therethrough; Fig.- 6 isa detail side elevation of the wedge device with its parts assembled; and,',Fig.' 7 is a perspective view being broken away. i

In the drawings, thenumeral 1 designates the elongated rectangular. body .of the gage which is provided in its front face with a longitudinal groove 2' in communication with its alining terminal openings 3 and 4c,- the latter being Zthreaded for connection with the pipes 5 and 6. The outer portion of the body groove is enlarged as at 7. to

form a glass socket in which the water glass Specification of Letters Patent.

8 is adapted to be positioned so as to project casing so asto holdfthe glass 8* in contact with the front wall of the'casing. Alongitudinal view opening 15' is provided'inthe saidfront wall of the casing so "that the in terior of the body groove 2 may be viewed through the glass. The lower end of-the glassis supported by the head'l6 provided at the lowerend ofthe casing, and its upper endis secured'lby the enlargement 17 which is formedupon the up'perend of the body 1. .A gasket 18 of soft fiber is positioned be tween the front face of the glass and the preferably of 9 i front wall of the casing surroundingthe view opening. Lateral "flanges 19 are formed upon the upper end of the body 1 for engagement with the upper end ofthe casing. The pipe 6 which is secured to the lower-"end of the body leXtends through an I 1 opening 20 provided in the-casing head 16.

The lower end of the casing 11 is provided with-an extension 21 in rear of the opening, 20 whose, head 22 is provided with an" opening 23 for the reception of an adjust ingscrew 24:. The operating head 25j0f.

this screw is adapted to bear against a washer'26 positioned against the under face of'the' head 22. Theinner threaded end. portion'27 of the screwisadjustably engaged within the I threaded v I longitudinal "opening 28 provided in the lower end of afclamping wedge .29. The rear *face 30 of fthe wedge 29 is transversely convex andiis inclined forwardly and downwardly .for' en gagement 'withthe .correspondingly'spaced and inclined inner-face 31 oft he rear 'cas-J ing'wall. The front'face ofthe wedge is provided with longitudinal, grooves32' open ing through its side faces and whose inner surfaces are longitudinally concave. The intervening portion 33of the front face of the wedgerzis-cut. away'to a slight'extent,

whereby the said face- W111 be'spaced slightly be disposed angularly with respect to the wedge without spacing the flanges there' from at'any point, which would impair the sustaining and reinforclng function of the wedge.

Whenthe parts of the gage are assembled,

the face plate of'the wedge device will fit snugly against the rear face of the body 1 even though the same may be inclined with respect to the longitudinal axis of-the-casing, due'to inequalities in the construction .of the water glassor the gaskets-employed in connection therewith. vThe glass or I gaskets may be tapered longitudinally without' affecting the even engagement of the face plate of the wedge device with the body 1, owing to the pivotal mounting of the face plate upon the wedge body. As

the wedge is drawn downwardlyby operation of the adjusting screw 24;, the face plate will continue to bearagainst the body 1 evenlythroughout its area, and the water glass consequently willcbe clamped in position and reinforced effectively throughout its marginal area. There can be no danger of breakage when the glass is sustained in What is claimedis:
